It is argued that the hammer first depicted on the last coin type of Regnald I (c.919-21) at York was a craftsman’s tool symbolising urban prosperity, that the accompanying depiction of a bow and arrow symbolised rural wealth, that the sword of the subsequent sword St. Peter type was the sword of St. Peter intended as a symbol of the Christian rejection of violence, and that the hammer depicted in association with the sword on this type refers to Isaiah 2.4 in order to reinforce this rejection of violence.
